PAINTBRUBH-FERRULE AND METHOD OF MAKING THE SAME.

Specification of Letters ratent.

Patented Apr. 26,1921.

Application filed February 10, 1920. Serial No. 357,501.

T 0 all whom it may concern lie it known that I, FnaNu Jonuonn, a citizenof the United States, residing at 1007 Decatur street, Brooklyn, co'unty of Kings, and State ofNew York, have invented certain new and useful Improvements in Paintbrush-Ferrules and Methods of Making the Same, fully described and represented in the following specification and the accompanying drawings, forming a art of the same.

his invention relates to an improved process for the manufacture of a flat brush formed of a flat tuft of bristles and connected with a round handle, and the object of the invention is to furnish an improved means of securing together the flat ferrule which embraces the bristles and the hollow shank by which the wooden handle is attached to the ferrule.

Heretofore a cap has been secured upon the ferrule in an imperfect manner so that no water-tight connection was effected and great injury has with this construction resulted to the bristles when the brush was left soaking in water.

The imperfection in the union of the cap and ferrule arose from the fact that the bristles had commonly been inserted in the ferrule before the cap was secured thereto. thus straining the ferrule out of its normal Shape and rendering it impossible to close its upper end by a rap having a flange ex tended all around its margin.

A continuous flange is' absolutely necessary to mak a strong and uniform joint around the top end of the ferrule, and such caps in themselves could be made with perfect uniformity but could not be fitted upon the ends of ferrules when subjected to the treatment they receive in fitting the bristles therein, which, necessarily pushes the flat sides of the ferrule apart; and the caphas therefore been commonly made with a soldering flange upon two parallel sides and one end, leaving the other end destitute of the flange and adapted to pro ject over one edge of the ferrule when the cap was soldered thereon.

.Such projection compensated for variations in the dimensions of the ferrule. The projecting portion is readily cut off, and this end of the cap therefore has no flange to hold it to the ferrule.

' When flanges made in this defective mannor were put into use any blows upon the ferrule near the cap where the cap was destitute of the flange operated to open the joint at their junction, and permit access of water to the bristles inside when the flange was soaked in water thus causing injury to the brush.

The ferrule of the brush is frequently subjected to such strains, as whenknocking the paint out of the brush by a blow against the paint-pot.

To avoid this defective construction I reverse the ordinary process of manufacture and secure the cap upon the ferrule before the bristles are inserted in the ferrule, which method of operation pcrmitsthe' manufacture of ferrules and caps of perfect uniformity and interchangeability so that the caps can be flanged around their entire margin and embrace the entire upper end of the ferrule.

When such a cap is used a hollow metallic shank is attached to the center'of the cap to receive the wooden handle of the paintbrush and my process of manufacture permits such hollow shank to be soldered to the cap before or after it is secured upon the ferrule.

The invention will be understood by reference to the annexed drawing, in which Figure 1 is a perspective view of the ferrule: Fig. 2 is a perspective view of an inverted rap with continuous flange around its margin; Fig. 3 shows the cap and ferrule sci-loud together by soldering the flange to the ferrule; and Fig. 4 is an elevation of the ferrule completed, with a hollow socket for the lll'llslhhfifltllfi secured to the cap and ferrule by soldered tongues.

a designates the lower end of the ferrule, and b the upper end to which the cape is secured by the marginal flange c which is made to snugly embrace the u per end of the ferrule and be soldere thereto around the entire periphery.

With such construction the union of the cap and ferrule cannot be disturbed by any use to which a paint brush is subjected.

A. wooden handle may be used with the ferrule, (I being a hollow metal shank to fit tightly upon the handle, and tongues attached to opposite sides of'the shank to fit over the opposite fiat sides of the ferrule.

When soldered thereto the shank is rigidly connected with the ferrule and the handle is rigidly connected with the brush.

By my process the tuft of bristles is sha ed to fit snugly within the ferrule by hol ing them in a suitable mold, while their butts are glued together until the glue sets and hardens sufficiently to hold the bristles in a proper position while fitting them within the ferrule.

It will be seen from the above description that the roper connection of the cap with the ferrul is effected by making them of perfectly uniform shape, and Soldering them together before the ferrule is deformed by inserting bristles therein.

I am aware that a metallic ferrule and handle have been made in one piece, and also a cap in one piece with a ferrule, and I therefore disclaim such construction,

It is also old to secure the edge of a cap to a flat shell of the same shape as the ferrule and adapted to slip over and inclose a reat part of the ferrule before it is sol ered thereto. This construction is adapted for manufacturing the heavier sizes of paint brushes, but it involves more parts than mine, which does not require a reinforcing shell, and it is adapted for the manufacture of the smaller sizes of paint brushes for which it has ample strength.

Having thus set forth the nature of the invention what is claimed herein is:

1. The mcthod of making a flat paint brush, which consists in separately making a flat ferrule open at both ends, and a cap having a narrow flan 'eadapted to [it over one end of the ferru e and provided with a hollow shank having integral tongues projected transversely to the flange, and finally Soldering the flange of the cap and the tongues to the top end and sides of the ferrule respectively.

2. The combination, with a fiat metallic ferrule, of a cap having a narrow flange upon its entire margin soldered to the entire periphery at one end of the ferrule, and a hollow metallic shank attached to the center of the cap and provided with integral tongues secured upon the opposite flat sides of the ferrule.

In testimony whereof I have hereunto set my hand.

FRANK JOERGER.
